Hall of Fame wide receiver and former San Franciso 49er Jerry Rice weighed in on Twitter regarding current 49er backup QB Colin Kaepernick’s decision to remain seated during the national anthem before football games.

On Friday, Kaepernick chose not to stand up during the national anthem before Friday’s preseason game against the Green Bay Packers. Many people, including Jerry Rice, are criticizing Kaepernick for his decision not to stand.

Rice tweeted out that he was not in favor or Kaepernick’s decision and said that he should not disrespect the flag. Rice also seemed to criticize the Black Lives Matter movement with his tweet.

“All lives matter. So much going on in this world today. Can we all just get along! Colin, I respect your stance but don’t disrespect the Flag,” Rice tweeted.

In just a few hours, Rice’s tweet was liked and retweeted thousands of times and spread across the internet by many people upset with Rice’s comments.

Kaepernick said he has sat during the national anthem for three preseason games and will continue to do so during the season to protest the “oppression of black people and people of color.” He said that he will not stand for the anthem until something has changed in the United States.
